While taking their usual bath, the boys discuss how much Kyotaro is like an old man. The next day, when they go to school, they find themselves exhausted by climbing up the stairs... and learn that they're all becoming old men!
I'd rather not sacrifice my youth 
just to get out of class, though...
لكن أفضّل ألّا أضحّي بشبابي فقط
...لأجل التغيّب عن الدرس
Ich will aber lieber zur Schule gehen,
als so stark zu altern.
Preferiría no sacrificar
mi juventud solo por no ir a clases.
Preferiría no sacrificar
mi juventud solo por no ir a clase.
T’es prêt à zapper ta jeunesse
si c’est pour pas aller en cours…
Preferirei non sacrificare la mia giovinezza
solo per fuggire dalle lezioni...
Mas eu preferia não sacrificar minha
 juventude só para faltar nas aulas...
Я бы не стал расставаться
с молодостью ради такого...
